when I took my laptop to the service station, he took it inside and brought back switched on within five minutes. I asked him how he did it, he said you have to short the battery terminals inside. but he will not disclose which ones.
Battery terminal has seven pins, 1,2 & 3 are connected by red wires and 5,6 & 7 are black wires. Pin 4 is blank. someone said, if you short 3 & 4 it will turn on. But it did not work.
Maybe some body knows the trick for this particular brand (CompBook).
Thanks in advance.
